PPPEvent:

Serial2/0 LCP Open Event state initial

//On interface Serial 2/0, the LCP state machine was opened and was in the initial state.

*0.784906 Sysname PPP/8/debug2:

PPPState Change:

Serial2/0 LCP : initial --> starting

//LCP moved from the initial state to the starting state.

*0.784906 Sysname PPP/8/debug2:

PPPEvent:

Serial2/0 LCP Lower Up Event state starting

//A lower layer up event was reported for LCP. The LCP state machine was in the starting state.

//Interface Serial 2/0 sent a 35-byte LCP packet. The type of the packet is Configure-Request, its ID is 2a, and its length is 31 bytes with the header removed. The LCP state machine transited to the request sent state as a result. The packet contains these configuration options for negotiation: MRU (the TLV length is four bytes, and the desired MRU value is 05dc); the authentication protocol (the TLV length is four bytes and the desired authentication protocol is PAP); the magic-number (the TLV length is 6 bytes, and the value is 31180c00); the MRRU
